EN 471 High Visibility Clothing Standard
GUIDE FOR DIVISION OF CLASSES
Depending on its characteristics, clothing which is considered
high visibility can belong to one of three classes which are indicated
by the standard.
- CLASS 3:
The refractive strip must have a minimum height of at least 50 mm and a
total minimum surface area of at least 0.20 sq m. The fluorescent
background material must have a surface area of at least of 0.80 sq. m.
- CLASE2:
The refractive strip must have a minimum height of at least 50 mm and a
total minimum surface area of at least 0.13 sq m.
The fluorescent background material must have a surface area of at
least of 0.50 sq. m.
- CLASS 1:
The reflective strip must have a minimum surface area of 0.10 sq. m.
The fluorescent background material must have a surface area of at
least of 0.14 sq. m.
For example, garments such as jackets and pants are in class
3, high visibility colour sleeved jackets are in class 2, life jackets
are in class 2, while suspenders fall in class 1.
In addition to surface area requirements, certain regulations
regarding location, distance of the reflective strips and minimum risks
of discontinuity between the strips must be followed. For example, if
you wear a certified jacket that is open with a break in reflective
strip of more than 3 cm, it is as if you are wearing an non-certified
jacket.
In this regard, a similarly certified vest or T-shirt should
also be worn under the jacket or shirt.
Cleaning is also important. When a garment is dirty, it loses
its high visibility properties and must be washed. Washing cycles that
the garment can resist without losing its features must be indicated in
the marking.
Marking: The markings on the clothing label should indicate:
- Brand or identification marks of the manufacturer or
representative
- Name or product code
- Size
- Reference standard
- Maintenance instructions no of washing cycles
- Pictogram
Pictogram where the first number (X) indicates the class of
material and the second number (Y) indicates the class of the
refractive strip such as the coefficient of luminous intensity.
